Supported QoS rule types
~~~~~~~~~~~~~~~~~~~~~~~~
Any plug-in or ml2 mechanism driver can claim support for some QoS rule types
by providing a plug-in/driver class property called
``supported_qos_rule_types`` that returns a list of strings that correspond
to `QoS rule types
<https://git.openstack.org/cgit/openstack/neutron/tree/neutron/services/qos/qos_consts.py>`_.
QoS supported rule types are now available as ``VALID_RULE_TYPES`` in `QoS rule types
<https://git.openstack.org/cgit/openstack/neutron-lib/tree/neutron_lib/services/qos/constants.py>`_:
* bandwidth_limit: Bandwidth limitations on networks or ports.
* dscp_marking: Marking network traffic with a DSCP value.
* minimum_bandwidth: Minimum bandwidth constraints on certain types of traffic.
Any QoS driver can claim support for some QoS rule types
by providing a driver property called
``supported_rules``, the QoS driver manager will recalculate rule types
dynamically that the QoS driver supports.
The following table shows the Networking back ends, QoS supported rules, and
traffic directions (from the VM point of view).
